MethodResolver

Struct MethodResolver 

Source
pub struct MethodResolver<T>
where T: Hasher,
{ /* private fields */ }
Expand description

Uses an underlying hashing function (blake2b by convention) to generate method numbers from method names.

Implementations§

Source§

impl<T> MethodResolver<T>
where T: Hasher,

Source

pub fn new(hasher: T) -> MethodResolver<T>

Creates a MethodResolver with an instance of a hasher (blake2b by convention).

Source

pub fn method_number(&self, method_name: &str) -> Result<u64, MethodNameErr>

Generates a standard FRC-0042 compliant method number.

The method number is calculated as the first four bytes of hash(method-name). The name Constructor is always hashed to 1 and other method names that hash to 0 or 1 are avoided via rejection sampling.
